    摘要:

    黄河是中国北方最大河流,其发育和形成对中国北部三大地势阶梯的建立具有重要指示意义。但到目前为止,有关黄河的形成时代存在较大争议。基于此,本文对鲁中山区的河流进行碎屑锆石U-Pb年龄分析(n=240),与流入渤海湾盆地的辽河、滦河、永定河、滹沱河、漳河和黄河的锆石U-Pb年龄进行对比,从而确定黄河因具有显著的新元古代峰值年龄(1000~700 Ma)成为渤海湾盆地的特征河流。我们将黄河下游的碎屑锆石U-Pb峰值年龄与渤海湾盆地中新统钻孔的锆石U-Pb峰值年龄进行对比,结合多维判别图(MDS),结果表明黄河在中新世未进入渤海湾盆地。

    Abstract:

    The development and formation of the Yellow River, the largest river in North China, is of great significance to the establishment of the three terrains in North China. But so far, there is a great controversy about the formation age of the Yellow River. In this case, we have carried out the analysis of detrital zircon U-Pb ages (n=240) of the rivers derived from the Central Luzhong Shan, compared with those of the Liao River, Luan River, Yongding River, Hutuo River, Zhang River and the Yellow River flowing into the Bohai Bay Basin. The results show that the Yellow River is the characteristic river of the Bohai Bay Basin due to its significant Neoproterozoic peak ages (1000~700 Ma). The systematic evolution information of big river kept by the clastic sediments deposited in the downstream of river, therefore, we compared the detrital zircon U-Pb peak age of the lower reaches of the Yellow River with the drilling cores within the Bohai Bay Basin. Combining multi-dimensional discrimination diagram (MDS) results, it shows that the Yellow River did not flow into the Bohai Bay Basin during the Miocene.
